James Charles is not the first artist to use currency as inspiration for his original art, but his works are the geekiest I’ve seen in a while.

While some items of the “American Iconomics“series might have ou think that Charles simply manipulated the faces on genuine dollar bills, it’s just an illusion. The artist kept the original outline of the bills, but replaced the faces of former American presidents with those of famous pop icons like Jimi Hendrix, Master Yoda, Mr. Spock, Sarah Palin, and many others. In sone cases he simply drew over the faces of the presidents to give them a whole new look, but every one of his pop-culture dollars comes with a sarcastic and funny line of text.

The “American Iconomics” collection is currently on display at San Francisco’s Shooting Gallery, where pop-art fans can purchase their favorite artworks for anywhere between $600 and $1,000.
